Abstract
"IMPROVEMENTS IN THE CONSTRUCTION OF LOADS FOR WRITING ELEMENTS" characterized in that on the appropriate end of the reservoir body a metallic tubing carrying the writing tip is fitted with pressure, provided with a circular projection that limits the length of the housing, acting in addition as seat of the upper end, narrower, of a conical spring that also supports by its greater perimeter on the appropriate staggering of the outer body of the writer element, to facilitate the retractability of said load.
